OAKLAND — A man shot multiple times Sunday afternoon at an East Oakland bus stop remained in grave condition Monday with life-threatening wounds, police said.

The man’s name and age were not released.

No arrests had been made as of Monday morning and police were still trying to establish a motive.

The shooting happened about 3:46 p.m. Sunday in the 5900 block of Foothill Boulevard.

Police said the man was approached on foot by a gunman who shot him more than once. The gunman then fled in a car.

Sunday’s shooting happened less than two blocks away from where five people attending a birthday party were wounded by a gunman on Jan. 13. That shooting happened about 8 p.m. in the 2600 block of Seminary Avenue.

Four men, ages 19, 20, 21 and 27, all from Oakland, and a 20-year-old Richmond man were hit in their legs by a gunman firing from across the street. They have all since been released from a hospital.

Police don’t think at this time the two shootings are related.
